I put an injector, area 67, injector setup in one of my Charvels with 250K pots (no load for tone) and I flat out love it. My favorite bridge single I've used as a high gain player. It's fatter than a typical single but nowhere near humbucker fat, you can still tell it's got some single coil vibe to it. Even under crazy high gain of Ch3 of my 5150III there's still loads of note clarity. I hesitate to call it P90ish but I guess some would consider it similar since it seems to walk that line between fat single and hum like a P90 can.
Like Badronald said the tone knob really works well with it too. It's one of my few guitars with a tone knob and the only one I actually use the tone knob on haha. With mine being no load when on 10 it's tighter, brighter and edgy (not in a bad way) and as you roll it back it warms up and fattens up so you can really alter the way it sounds for either a chunky rhythm or to get it to really cut through. I've never been a fan of tone knobs on bridge humbuckers since to me as you roll it back it just loses life thus why all my other guitars have no tone knobs since they all have hums in the bridge. With the injector it just becomes more versatile more like an actual single coil in that way despite it being stacked and fatter to begin with.
